Inventor: MIURA TOSHINORI
IPC: H01L29/74
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering in breakdown voltage near the end of an N type emitter layer. SOLUTION: In a mask pattern 7 of a mask for forming a P type gate layer 4, a central section 7a (near a central section 3a of an N type emitter layer 3) of the mask pattern 7 is formed expanded more than an end section 7b (near an end section 3b of the N type emitter layer 3) of the mask pattern 7. By using a mask having such a mask pattern 7, the distances between a P type gate layer 4 and the central section 3a and the end section 3b of the N type emitter layer 3 are respectively controlled, and the P type gate layer 4 can be formed around the N type emitter layer 3. Consequently, the breakdown voltage near the end section 3b of the N type emitter layer 3 becomes higher than that near the central section 3a of the N type emitter layer 3, thus preventing concentration of current in an SI thyristor.

Title: Bearing material having superior wearing resistance
Inventor: MORI SANAE
IPC: C10N10/08
Filed: 1982-12-03
Abstract: PURPOSE:To improve a material in its wearing resistance property, by impregnating a back metal with a composition including a specific percent of component selected from among resin groups of tetrafluoroethylene-ethylene copolymer, vinylidene fluoride, chlorotrifluoroethylene, and fluoroethylenepropylene-ether. CONSTITUTION:0.1-50vol.% of component selected from among a group of resins of tetrafluoroethylene-ethylene copolymer ETFE, vinylidene fluoride PVDF, chlorotrifluoroethylene PCTFE and fluoroethylenepropylene-ether EPE and other remaining composition substantially composed of PTFE are impregnated and coated over a port clearance and its surface area of porous metallic layer applied over a back metal. Where the vol.% of specific component selected is 0.1 or less, a wearing resistance is lowered, whereas the resistance is improved when the component becomes a principal one at the vol.% of 50 or more. However, because a friction coefficient and a friction temperature are increased at the same time, it is suitable for an optimum wearing resistance property to restrict the vol.% of specific component in the range of 0.1-50.

Title: Processor and system for data processing
Inventor: SHIRAI YOSHINORI
IPC: G06F12/00
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To perform a specific data processing even if the position of data writing to an IC memory card is not a specific fixed position by providing a means which retrieves the actual writing position when detecting a data file not being at the fixed position and writes a data flag to the fixed position. SOLUTION: A personal computer 3 writes the data file of measurement conditions to the mounted IC memory card 2. A measuring instrument 1 automatically takes a measurement under the measurement conditions and writes a file of the measurement result in a specific area on the IC memory card 2. Then when the data file of the measurement result is written, it is written to the predetermined fixed position different from the writing position of the data file of the measurement conditions. Therefore, even if the recording position of the data file on the IC memory card 2 is not the predetermined fixed position, the contents of the data file are rewritten to the fixed position on the side of the data processor, so the specific data processing can be performed.

Title: Weed stop apron block
Inventor: YAKUSHINJI KUNIAKI
IPC: E01C11/22
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To suppress the growth of weeds even if seeds of weeds adhere on a side face on a footwalk side of an apron block and an asphalt boundary face by providing one or a plurality of steplike knotched sections on a wall face on the footwalk side of the apron block in the shape of L character. SOLUTION: By providing steplike knotched sections 3 on a wall face 2 on a footwalk 9 side of an apron block 1 which is used to divide a line and the footwalk, is made of concrete, and is in the shape of L character, the number of the knotched sections 3 is increased adequately in places such as a field zone and a mountainous region where weeds are likely to grow comparatively. When the stepped section 3 is provided on the wall face 2 of the apron block 1, soil dust which invades through a boundary face between the wall face 2 and asphalt 11 does not enter down to the depth at which it reaches a layer 13 of soil because the wall face 2 and the boundary face of asphalt 11 are meandered properly to prevent the germination of weeds.  Even if weeds germinate, an amount of soil dust from which weeds get nutriment is insufficient or none so that roots of weeds become short, do not grow fully, and the growth of weeds is suppressed.
